Microstructure Characterization of Nanocrystalline Magnesium Ferrite Annealed at Elevated Temperatures by Rietveld Method
Figure 2
(a) X-ray powder diffraction patterns of 9 h ball-milled MgO-α-Fe2O3 mixture annealed at different temperatures for 1 h duration. The peak positions of different phases are shown as small solid bar markers at the bottom of the figure. (b) Indexed selected area electron diffraction pattern of Mg-ferrite powder after annealing the 9 h milled sample at 1473 K for 1 h duration.
